APPARATUS FOR SPINNING AND DOUBLINGCOTTO N, 86C.

SPECIFICATION forming part of Letters Patent No. 620,824, dated March 7, 1899. Application filed October 21, 1898- Serial No. 694,195- (No model.)

.for Letters Patent, Serial No. 663,669, was

filed by me on the 27th-day of December, 1897, the object of the present invention being to further improve the action of the drag or friction-brake upon the spindle.

Figure 1, Sheet 1, on the drawings hereunto annexed represents a sectional elevation of so much of a spinning or doubling frame as is necessary to illustrate the application of my invention thereto, and Fig. 2, Sheet 2, is a plan view of the same. Fig. 1, Sheet 1, is an elevation of the brakeframe detached and drawn to a larger scale, and Fig. 2 is a horizontal section of the same. Fig. 3 on Sheet 3 is a detached View of the chain and rack. Fig. 4 on the same sheet is an elevation, detached, of the adjustable stop; and Fig. 5 is a plan View of the same.

Referring to Figs. 1 and 2, Sheets 1 and 2 of the drawings, a is the spindle-rail; b, the lifting-rail; c, the spindle, and d the short tubular flier with cup-shaped enlargement.

I employ the same kind of friction-brake k as described in my previous specification, (see Figs. 1 and 2, enlarged views,) consisting of a light frame of wire hanging upon screws or pivots i, one on each side of the bolster h, which carries the spindle c, and provided with a tuft or roll of cotton or other fibrous substance Z, which is saturated with oil or other suitable lubricant and acts as a drag or brake upon the spindle, as well as lubricating it. I also employ a rocking shaft e, which is carried by suitable bearings be,- hind the spindles and near to the fixed spindle-rail a, which carries the bolsters h. Upon this rocking shaft I mount a series of arms f, carrying a rod or shaft g, the said arms or one or more of them being provided with a ratchet or pawl m, and upon the rod or shaft g I mount a ratchet-Wheel H.

To the horizontal arm 70 of the light-brakeframe is I attach one end of'a chain 0, which hangs down in a loop, as shown at Fig. 1, and has its other end coiled around the rod or shaft g, (see Fig. 2,) so that the weight of the front portion of the loop of chain hangs upon the arm 70 and causes the brake 70 Z to be pressed against the spindle cand by turning the rod or shaft 9 around by hand the length of the loop and consequent pressure of the drag or brake 70 Z upon the spindle 0 can be regulated in accordance with the count of yarn required to be spun, the ratchet or pawl m and the ratchet-wheel a holding the chain as it is raisedto the required position and preventing it from running back.

The rocking motion given to the shaft 6 is so regulated that the greatest drag is applied to the spindles at the moment when the yarn is being wound onto the largest diameter of the cop and is gradually lessened or withdrawn as it reaches the smallest diameter thereof, so that the amount of drag is always proportioned to the pull of the yarn on the spindles. This graduation of drag or pressure is effected by the alternate lengthening and shortening of the length of the loop of chain 0, which is effected by the falling and rising of the arms f, caused by the rocking motion of the shaft 6, and this rocking motion is given to it in the following manner: On the cam-shaft p of the machine I mount a cam q, provided with a gradual lift and a more or less sudden fall. Against this cam q works a bowl or roller r, carried bya lever s, which hangs upon a fulcrum at the back end of the frame, and to the front end of this-lever is connected one end of a chain 8, the other end of which is fixed to a round block or pulley 25, carried by the rocking shaft 6, and by these means the requisite rocking lHOhlOl1-ViZ., a gradual rise and a more or less rapid fallis given to the arms f and the rod or shaft g, which carries the rear ends of the looped chains 0, the position of the cams being such that the weight of the loops of the chains decreases'as the yarn is wound on the smaller diameter of the cop and increases as it approaches the larger diameter of the same, so

as to equalize the drag of the yarn on the spindle. By connecting the blocks or pulleys 2! on the opposite sides of the machine with each other by means of a chain to, attached to the top of one block and the bottom of the other, as shown at Fig. 1, one cam q and lever s will sufiice for both sides of the frame, the Weight of the arms f and chains serving to keep the bowl or roller 0" always in contact with the cam q.

The chain 0 is preferably made in a graduated form, (see Fig. 3,) the links at each end being very light and the central portion, which forms the loop, being much heavier, and instead of connecting the end of this chain directly to the rod or shaft g I interpose between the end of the chain 0 and the said shaft a kind of rack 1 made of wire, (see Fig. 3,) having two or three eyes or loops 1) at different heights, so that by hooking the end of the chain 0 into one or other of the eyes of these loops the chain may be lengthened so as to regulate its weight to the drag required.

In this case the rod or bar g' may be fixed in the arms f, and the ratchet m and ratchetwheel 97. may be dispensed with. (See Fig. 1.)

The lift of the chains is always the same, but the fall thereof may be regulated as required by means of an adjustable stop (see Figs. 4 and 5) which prevents the armsfon the rocking shaft e from falling beyond a certain point, and by altering the position of this stop by hand the drop of the bowl or roller r on the cam q, and consequently the fall of the chains 0, can be diminished to any required degree. At or near one end of the rocking shaft 6 (see Figs. 4 and 5) I fix for this purpose a short finger 10, which acts against the stop 00, which is adjustable by turning the screw y by hand. When this stop is raised, the finger to coming against it arrests the downward motion of the rocking shaft 6 and makes the drag on the spindle lighter, and by lowering the same a greater weight of chain 0 is allowed to act, and thus the drag or pressure of the brake 70 Z against the spindle c is increased.

I claim as my invention- 1. In apparatus for spinning and doubling cotton and other fibrous substances, the combination of a spindle and a light rocking brakeframe therefor, with a rocking shaft having arms and a rod mounted therein, and a looped chain graduated to beheavier at the center than at the ends, having one end attached to said brake-frame and the other end attached to said rod, as and for the purpose specified.

2. In spindle brake apparatus for spinning and doubling the combination of a rocking brake-frame and chain connected thereto with a rocking shaft having arms and a rod or shaft round which one end of the looped chain is wound, and a ratchet and ratchet-wheel on said arms and rod, whereby on turning the said rod or shaft round by hand the loop of chain may be lengthened or shortened, substantially as specified.

3. In spindle brake apparatus for spinning and doubling, the combination of a rocking brake-frame and chain connected thereto with a rocking shaft to which the chain is also connected, an actuating cam and lever, a finger on the rock-shaft and an adjustable stop for limiting the amount of fall of the looped chains in the manner and for the purpose.
